17
.. These may require users to change the way they use Bazaar.
22
.. New commands, options, etc that users may wish to try out.
27
.. Improvements to existing commands, especially improved performance
28
or memory usage, or better results.
33
.. Fixes for situations where bzr would previously crash or give incorrect
34
or undesirable results.
36
* Don't fail with traceback if `bzr serve` is running as a service on Windows,
37
and there is no USERNAME, nor BZR_EMAIL or other whoami-related environment
38
variables set. (Alexander Belchenko, Bug #660174)
43
.. Improved or updated documentation.
45
* Updated the "Using stacked branches" section of the user guide to
46
describe committing to stacked branches and expanded its discussion of
47
pushing a stcked branch. (Andrew Bennetts)
52
.. Changes that may require updates in plugins or other code that uses
58
.. Major internal changes, unlikely to be visible to users or plugin
59
developers, but interesting for bzr developers.
64
.. Fixes and changes that are only relevant to bzr's test framework and
65
suite. This can include new facilities for writing tests, fixes to
66
spurious test failures and changes to the way things should be tested.
68
* Remove the deprecation decorators for ``failUnlessExists`` and
69
``failIfExists``. The deprecation "will" occur in 2.4, not
70
before. Providing the wrappers is enough as far as 2.3 is concerned.

This fixed a bug in the test suite triggered by python-2.7 deprecating some

*****************************
116
* Getting all entries from ``CHKInventory.iter_entries_by_dir()`` has been
117
sped up dramatically for large trees. Iterating by dir is not the best
118
way to load data from a CHK inventory, so it preloads all the items in
119
the correct order. (With the gcc-tree, this changes it (re)reading 8GB
120
of CHK data, down to just 150MB.) This has noticeable affects for things
121
like building checkouts, etc. (John Arbash Meinel, #737234)
126
* Bazaar now infers the default user email address on Unix from the local
127
account name plus the contents of ``/etc/mailname`` if that file exists.
128
In particular, this means that committing as root through etckeeper will
129
normally not require running ``bzr whoami`` first.
130
(Martin Pool, #616878)
132
* ``bzr merge --preview --pull`` should respect the ``--preview`` option
133
first, and not actually change the branch tip revision.
134
(John Arbash Meinel, Dennis Duchier, #760152)
136
* ``bzr push`` into a repository (that doesn't have a branch), will no
137
longer copy all revisions in the repository. Only the ones in the
138
ancestry of the source branch, like it does in all other cases.
139
(John Arbash Meinel, #465517)
141
* Fix ``UnboundLocalError: local variable 'lock_url' in wait_lock`` error,
142
especially while trying to save configuration from QBzr.
143
(Martin Pool, #733136)
145
* Fix "Unable to obtain lock" error when pushing to a bound branch if tags
146
had changed. Bazaar was attempting to open and lock the master branch
147
twice in this case. (Andrew Bennetts, #733350)
149
* Standalone bzr.exe installation on Windows: user can put additional python
150
libraries into ``site-packages`` subdirectory of the installation directory,
151
this might be required for "installing" extra dependencies for some plugins.
152
(Alexander Belchenko, #743256)
154
* When reporting a crash without apport, don't print the full list of
155
plugins because it's often too long.
156
(Martin Pool, #716389)
167
* FreeBSD8 has switched to python-2.7 which revealed a re-occurrence of a test
168
failure in the launchpad plugin. ``xmlrpclib.py`` on natty carries a patch
169
that is not in python-2.7 upstream and masked the issue. An additional fix
170
has been added in the interim
171
(<http://psf.upfronthosting.co.za/roundup/tracker/issue8194> should be fixed
172
in python > 2.7.1). (Vincent Ladeuil, #654733)
179
This is a bugfix release. Upgrading is recommended for all users of earlier
185
.. Fixes for situations where bzr would previously crash or give incorrect
186
or undesirable results.
188
* Correctly resolve text conflicts for files in subdirs.
189
(Vincent Ladeuil, #715058)
191
* Fix "AssertionError: repository.user_url ... does not match URL from
192
server response" when reusing a smart transport.
193
(Andrew Bennetts, #726584)
195
* Restore proper logging of bytes transferred. We accidentally reset the
196
counter when commands finished before we logged the total transferred.
197
(John Arbash Meinel, #713258)
204
This release marks the start of another long-term-stable series. From here, we
205
will only make bugfix releases on the 2.3 series (2.3.1, etc, and support it
206
until August 2012), while 2.4 will become our new development series. The 2.1
207
and 2.2 series will also continue to get bugfixes. (Currently 2.0 is planned
208
to be EOLed circa September 2011 and will receive only critical bugfixes.)
210
This is a bugfix and polish release over the 2.2 series, with a large number
211
of bugs fixed (>130), and some performance improvements. Some features have
212
been enhanced including commits on stacked branches, upgrades of related
213
branches, shortcut URL schemes for ubuntu and debian on launchpad and better
216
Only bugfixes from other stables series have been included since 2.3b5 so all
217
known fixed bugs are included here.
219
Users are encouraged to upgrade from the other stable series.
226
This is the fifth and **last** beta of the 2.3 series, leading up to a 2.3.0
227
release in February. Beta releases are suitable for everyday use but may cause
228
some incompatibilities with plugins.
230
2.3b5 includes bug fixes for committing to stacked branches, smoother upgrades
231
of multiple branches, compatibility with python-2.7, full test suite passing
232
on Ubuntu Natty and windows, less round-trips for several smart server
233
operations, better support text conflicts resolve actions and some more.
235
All known fixed bugs in other series (2.0, 2.1, 2.2) are also included here.
237
External Compatibility Breaks
238
*****************************
245
* A redundant parent inventories calculation was removed from
246
``fetch.py``, as ``Repository.insert_stream`` already reports any
247
missing inventories. This removes at least one network roundtrip when
248
pushing to a stacked branch. (Andrew Bennetts)
250
* ``ControlDir.sprout`` no longer opens the target repository more than
251
once. This avoids some unnecessary IO, and removes a network roundtrip
252
when doing ``bzr branch`` to a smart server URL. (Andrew Bennetts)
254
* ``bzr modified`` now read-locks the working tree (and branch and
255
repository) just once. (Andrew Bennetts)
257
* ``bzr resolve`` now accepts ``--take-this`` and ``--take-other`` actions
258
for text conflicts. This *replace* the whole file with the content
259
designated by the action. This will *ignore* all differences that would
260
have been merge cleanly otherwise. (Vincent Ladeuil, #638451)
262
* ``bzr tags``'s "sort" argument now allows registering custom sort
263
methods using the ``bzrlib.tag.tag_sort_methods`` registry.
264
(Jelmer Vernooij, #701244)
266
* ``bt.test_http`` was breaking ``os.environ`` by erasing the values saved by
267
``TestCase`` leading to ``bt.test_import_tariff`` failures.
268
(Vincent Ladeuil, #690563)
270
* ``upgrade`` now upgrades dependent branches when a shared repository is
271
specified. It also supports new options: ``--dry-run`` for showing what
272
will happen and ``--clean`` to remove the backup directory on successful
273
completion. (Ian Clatworthy, Matthew Fuller, #89830, #374734, #422450)
278
.. Fixes for situations where bzr would previously crash or give incorrect
279
or undesirable results.
281
* Avoid leaking SSH subprocess communication socket into unrelated child
282
processes, which could cause bzr to hang on exit. (Max Bowsher, #696285)
284
* ``bzr break-lock`` on a corrupted lock file works correctly, rather than
285
raising a PermissionDenied error. We were accidentally holding open the
286
file we were trying to delete. (John Arbash Meinel, #659978)
288
* ``bzr update`` in a checkout of a readonly branch works again, without
289
trying to set the tags in the master branch. This had been broken by the
290
bug fix for bug #603395. (John Arbash Meinel, #701212)
292
* Per-transport tests now prefer to use ``Transport.get_bytes()`` rather
293
than ``Transport.get().read()``. The SFTP code uses an async message to
294
close the file handle if you let the handle die from refcounting, while
295
it uses a synchronous message if you close it directly. This should help
296
prevent random test suite failures from race conditions.
297
(John Arbash Meinel, #681047)
299
* Stop using ``bzrlib.tuned_gzip.GzipFile``. It is incompatible with
300
python-2.7 and was only used for Knit format repositories, which haven't
301
been recommended since 2007. The file itself will be removed in the next
302
release. (John Arbash Meinel)
304
* The BZR_COLUMNS environment variable can be set to 0 to indicate no
305
limitation on the width of the terminal. (Neil Martinsen-Burrell, #675652)
307
* Treat WSAECONNABORTED the same as WSAECONNRESET for the purposes of
308
considering a smart data stream as being interrupted. This fixes a
309
failure in the windows test suite, that was trying to ensure we cleanly
310
handled a server disconnect. (John Arbash Meinel, #581311, #686587)
312
* Unshelving changes that occur in a now-unversioned directory now restore
313
the directory properly rather than crashing.
314
(John Arbash Meinel, #389674)
316
* You are now able to commit directly to a stacked branch. Any needed
317
parent inventories will be filled in as part of the commit process.
318
(John Arbash Meinel, #375013)
323
* Better document the rules to update the bzr freshmeat page when
324
doing a release. (Vincent Ladeuil, #690515)
329
* ``Branch.sprout``, ``BranchFormat.initalize`` and
330
``ControlDir.create_branch`` now take an optional ``repository`` keyword
331
argument, and ``BranchFormat.open`` now takes an optional
332
``found_repository`` keyword argument. These provide the repository
333
object for new branch object to use (for cases when the caller has
334
already opened that repository). Implementations of these APIs will
335
need to be updated to accept these arguments. (Andrew Bennetts)
337
* ``bzrlib.tuned_gzip.GzipFile`` is now deprecated and will be removed in
338
the bzr-2.4 series. Code that was using it can just use the python
339
stdlib ``gzip.GzipFile``. (John Arbash Meinel)
345
* ``bzrlib.tests`` defines ``isolated_environ`` with the definitions of all
346
the environment variables the tests should care about. It also defines
347
``override_os_environ`` and ``restore_os_environ`` to properly implement
348
isolation from ``os.environ`` for tests. ``bzrlib.tests`` now defines a
349
``DocTestSuite`` class using this facility for all ``bzrlib``
350
doctests. (Vincent Ladeuil, #321320)
352
* Catch exceptions related to bug #637821 during test cleanup to avoid
353
spurious failures. (Vincent Ladeuil, #686008).
355
* Check sphinx compatibility for tests requiring older sphinx versions.
356
(Vincent Ladeuil, #688072)
358
* ``test_onto_transport`` in the Launchpad plugin can now run with Python
359
2.7. (Vincent Ladeuil, #654733)
361
* ``TestCase._captureVar`` and ``TestCase._old_env`` have been deleted due to
362
bug #690563. Test writers are encouraged to use ``TestCase.overrideEnv``
363
instead. (Vincent Ladeuil)
365
* ``TestDebuntuExpansions`` was escaping the test isolation by calling the
366
wrong base class ``setUp``. (Vincent Ladeuil, #684662)
373
This is the fourth beta of the 2.3 series, leading up to a 2.3.0 release in
374
February. Beta releases are suitable for everyday use but may cause some
375
incompatibilities with plugins.
377
2.3b4 includes bug fixes for the ``config`` command and conflict
378
resolution. More changes were made for the test scripts handling to make it
379
easier to add reproducing recipes to bugs.
381
It also includes bug fixes from the 2.2.2 release as well as the bug fixes
382
in the upcoming 2.0.7, 2.1.4 and 2.2.3 releases. This means that all known
383
fixed bugs at the time of this release are included.
386
External Compatibility Breaks
387
*****************************
394
* Bazaar now caches a branch's tags while that branch is read-locked.
395
This removes 1 network roundtrip from most interactions with a remote
396
branch. (Andrew Bennetts)
398
* ``bzr config <option>`` will now display only the value itself so scripts
399
can use it to query the currently active configuration. Displaying several
400
options matching a given regular expression is now controlled via the
401
``--all`` option. (Vincent Ladeuil, bug #670251)
403
* ``bzr resolve`` now reports the number of conflicts resolved and the
404
number of remaining conflicts. This provides a better feedback about the
405
whole resolution process. (Vincent Ladeuil)
407
* Read configuration files in $XDG_CONFIG_HOME/bazaar on Unix if there is
408
already a directory there. (Neil Martinsen-Burrell, #195397)
413
* Better message if there is an error while setting ownership of
414
``.bazaar`` directory. (Parth Malwankar, #657553)
416
* ``bzr config`` properly displays list values. (Vincent Ladeuil, #672382)
418
* ``bzr config`` will now respect option policies when displaying the value
419
and display the definition sections when appropriate.
420
(Vincent Ladeuil, #671050)
422
* Don't create commit message files in the current directory to avoid nasty
423
interactions with emacs (which tries to establish the status of the file
424
during the commit which breaks on windows). (Vincent Ladeuil, #673637)
426
* ``bzr resolve --take-other <file>`` will not crash anymore if ``<file>``
427
is involved in a text conflict (but the conflict is still not
428
resolved). (Vincent Ladeuil, #646961)
430
* Merge will now correctly locate a lca where there is a criss-cross merge
431
of a new root. (Gary van der Merwe, #588698)
433
* Report error if non-ASCII command option given. (Rory Yorke, #140563)
435
* ``tools/check-newsbug.py`` is now based on ``lp:hydrazine`` and no longer
436
crashes when encountering private bugs (they are just displayed as such).
437
(Vincent Ladeuil, #354985)
442
* ``BranchBuilder.build_snapshot`` now accepts parent_ids == [].
443
This can be used to create a new root in the graph. (Gary van der Merwe)
445
* Old repository development formats
446
RepositoryFormatCHK1 and RepositoryFormatCHK2 have been removed, and so
447
have the corresponding metadir format options ``development-rich-root``,
448
``development6-rich-root``, and ``development7-rich-root``.
453
* Add a null_output_matches_anything keyword argument with default False to
454
bzrlib.tests.script.ScriptRunner.run_script to specify that the command
455
output should not be checked (as opposed to expecting an empty output).
456
(Neil Martinsen-Burrell, #662509)
458
* Blank output section in scriptrunner tests no longer match any output.
459
Instead, use '...' as a wildcard if you don't care about the output.
460
(Martin Pool, #637830)
462
* Bump minimum testtools version required to run ``bzr selftest`` from 0.9.2
463
to 0.9.5 which will allow tests that need the fixed unicode handling to be
464
written. (Martin [gz])
466
* Introduce an ``overrideEnv()`` helper for tests that needs to change the
467
environment variables while respecting the isolation rules. Get rid of
468
TestCase._restoreEnvironment which is now useless.
469
(Vincent Ladeuil, #690563)
471
* Printing selftest results to a non-UTF-8 console will now escape characters
472
that can't be encoded rather than aborting the test run with an exception.
473
(Martin [gz], #633216)
481
External Compatibility Breaks
482
*****************************
489
* Add --no-tree option to 'bzr push' and 'bzr init' for creating a
490
new or mirrored branch without working trees.
491
(Matthew Gordon, #506730)
493
* ``bzr config`` is a new command that displays the configuration options for
494
a given directory. It accepts a glob to match against multiple options at
495
once. It can also be used to set or delete a configuration option in any
496
configuration file. (Vincent Ladeuil)
498
* New shortcut URL schemes ``ubuntu:`` and ``debianlp:`` access source
499
branches on Launchpad. E.g. ``bzr branch ubuntu:foo`` gives you the source
500
branch for project ``foo`` in the current distroseries for Ubuntu while
501
``bzr branch debianlp:lenny/foo`` gives you the source branch (on Launchpad)
502
for project ``foo`` in Debian Lenny.
503
(Barry Warsaw, #609186)
505
* Provide a configuration option "default_format" that controls the
506
default format for new branches created with ``bzr init``.
507
(Neil Martinsen-Burrell, #484101)
512
* Always set PATH in start_bzr.bat on Windows. (Matthäus G. Chajdas, #470264)
514
* ``bzr status -r X..Y`` was failing because RevisionTree didn't implement
515
``get_shelf_manager``. (John Arbash Meinel, #662053)
517
* Correctly add directory contents when the name was previously added as a
518
normal file, rather than throwing ``AttributeError: children`` during
519
smart_add. (Martin [gz], #251864)
521
* Correctly handle the ``--directory`` option for all code paths of
522
``resolve`` and ``shelve``, this was previously ignored when paths were
523
provided as parameters. When both are provided, ``--directory`` becomes
524
the base directory for the other paths. (Vincent Ladeuil, #670851)
526
* Correctly set the Content-Type header when HTTP POSTing to comply
527
with stricter web frameworks. (Vincent Ladeuil, #665100)
529
* Don't force openssh to use protocol=2, since that is now the default.
530
(Neil Martinsen-Burrell, #561061)
532
* Fix ``KeyError: 'port'`` when getting the stored password for an HTTP URL.
533
(Martin Pool, #654684)
535
* Make ``bzr tag --quiet`` really quiet. (Neil Martinsen-Burrell, #239523)
537
* Missing files (files bzr add'ed and then OS deleted) are now shown in ``bzr
538
status`` output. (Rory Yorke, #134168)
540
* ``NotBranchError`` no longer allows errors from calling
541
``bzrdir.open_repository()`` to propagate. This is unhelpful at best,
542
and at worst can trigger infinite loops in callers. (Andrew Bennetts)
544
* The ``branch.tags.merge_to(target_branch)`` API used by plugins such as
545
``bzr-builddeb`` now propagates changes to the master branch of the
546
target branch (if there is one). This makes it consistent with the
547
other tag APIs. (Andrew Bennetts, #603395)
549
* Windows installers no longer requires the Microsoft vcredist to be
550
installed. (Martin [gz], Gary van der Merwe, #632465)
555
* Add documentation of the ability to edit hunks when shelving.
556
(Neil Martinsen-Burrell, #517660)
558
* Be more specific about the meaning of revision ranges for ``bzr diff``.
559
(Neil Martinsen-Burrell, #247282)
561
* Document the comment character in the .bzrignore file, including a
562
workaround for ignore patterns that begin with #.
563
(Neil Martinsen-Burrell, #631515)
568
* Add ``bzrlib.pyutils`` module with helper functions for some Python
569
tasks such as resolving a dotted name to a Python object
570
(``get_named_object``). (Andrew Bennetts)
572
* ``bzrlib.tests.ForwardingResult`` no longer exists. Use
573
``testtools.ExtendedToOriginalDecorator`` instead. (Andrew Bennetts)
575
* ``known_hooks_key_to_parent_and_attribute`` in ``bzrlib.hooks`` has been
576
deprecated in favour of ``known_hooks.key_to_parent_and_attribute`` in
577
the same module. (Andrew Bennetts)
582
* ``tools/fixed-in.py`` find a bug in NEWS from its number or a regexp
583
matching the news entry and display the corresponding release, date, fix
584
authors and the news entry itself. (Vincent Ladeuil)
589
* Blank output section in scriptrunner tests no longer match any output.
590
Instead, use '...' as a wildcard if you don't care about the output.
591
(Martin Pool, #637830)
593
* ``bzr test-script script`` is a new command that runs a shell-like script
594
from an the ``script`` file. (Vincent Ladeuil)
596
* Fix spurious test failures on babune related to the http pipe cleanup and
597
get rid of some 'bytes left on the HTTP socket' useless log messages.
598
(Vincent Ladeuil, #655557)
600
* ``bzrlib.tests.per_workingtree.TestCaseWithWorkingTree.make_branch_builder``
601
respects its ``relpath`` parameter. (Vincent Ladeuil)
608
External Compatibility Breaks
609
*****************************
611
* The ``bzr tags`` command sorts tag names using a natural sort by
612
default (so tag2 sorts before tag10). The previous default was
613
strictly "asciibetical". That behavior is still available as ``bzr tags
614
--sort=alpha``. (Neil Martinsen-Burrell, #640760)
616
* ``BzrDir.generate_backup_name`` has been deprecated and replaced by a
617
private method. ``osutils.available_backup_name`` provides an extensible
618
replacement. This allowed the deprecation of
619
``bzrlib.transform.get_backup_name``,
620
``bzrlib.transform._get_backup_name`` and
621
``bzrlib.transform.TreeTransformBase.has_named_child``.
627
* Add ``mainline`` revision specifier, which selects the revision that
628
merged a specified revision into the mainline. (Aaron Bentley)
630
* Add ``annotate`` revision specifier, which selects the revision that
631
introduced a specified line of a file. (Aaron Bentley)
633
* Add ``-Dmem_dump`` debug flag, which uses meliae to dump memory to
634
a file upon an out of memory error.
635
(Karl Bielefeldt, #551391)
637
* ``bzr status`` now displays a summary of existing shelves after
638
the other status information. This is done using a ``post_status``
640
(Parth Malwankar, #403687)
642
* GNU lsh is now a supported lsh client; just set BZR_SSH to 'lsh'.
643
Also, bzr will recognize if the 'ssh' comand is a symlink to lsh.
644
(Matthew Gordon, #374700)
646
* The ``pull`` and ``update`` commands now take a ``--show-base``
647
option that, in the case of conflicts, shows the base revision text.
648
(Rory Yorke, #202374)
653
* ``bzr break-lock --force`` breaks the lock without prompting. (Before
654
using this, make sure the process holding the lock really is dead.)
655
(Martin Pool, #397315)
657
* ``bzr remove`` now takes a ``--no-backup`` option for when you don't want it
658
to backup anything, just delete it. This option used to be called ``--force``
659
which is now deprecated.
660
(Marius Kruger, #400554)
662
* When using the pycurl client module, Bazaar shows some of the text from
663
HTTP server error messages.
664
(Martin Pool, #656667)
669
* Don't force openssh to use protocol=2, since that is now the default.
670
(Neil Martinsen-Burrell, #561061)
672
* Fix signature of RemoteBzrDir.create_workingtree to match that of its
673
superclass. (Neil Martinsen-Burrell, Martin Pool, #524627)
675
* Fix traceback with python-2.7's xmlrpclib
676
(Toshio Kuratomi, #612096)
678
* Print junk rather than throwing a UnicodeDecodeError from ``bzr version-info``
679
when using the rio format (with non-ascii information) on a non-utf-8
680
terminal. (Andrej A Antonov, #518609)
682
* Treat all IO, OS, and socket errors consistently when establishing
683
SSH/SFTP connections via a subprocess. (Andrew Bennetts)
685
* ``unshelve --preview`` now can show diff in a non-ascii encoding.
686
(Andrej A Antonov, #518916)
688
* Deleting a versioned directory can leave orphans: unversioned files that
689
were present don't have a parent anymore. The
690
``bzr.transform.orphan_policy`` configuration option controls the ``bzr``
691
behaviour: ``conflict`` (the default) leave the orphans in place and
692
create a conflict for the directory, ``move`` create orphans named
693
``<file>.~#~`` in a ``bzr-orphans`` directory at the root of the working
694
tree. (Vincent Ladeuil, #323111)
702
* Correct the documentation for setting up the smart server with Apache.
703
(Neil Martinsen-Burrell, #311518)
705
* Fix rst typos in bzrlib/help_topics/en/conflict-types.txt.
706
(Vincent Ladeuil, #660943)
708
* Provide more detailed help on the Launchpad plugin at "bzr help
709
plugins/launchpad". (Neil Martinsen-Burrell, #589379)
711
* Suggest ``bzr revert`` for restoring locally deleted files in help text
712
for ``bzr update``. (John C Barstow, #191466)
717
* ``WorkingTree`` methods ``pull``, ``update``, and ``_update_tree``
718
now have an optional argument, ``show_base``, which is by default
719
False. This is flag is ultimately passed to ``merge.merge_inner``
720
in each case. (Rory Yorke, #202374)
725
* Small change to GroupCompressBlock to work more in terms of 'chunks'
726
rather than 'content' for its compressed storage. (John Arbash Meinel)
728
* When running ``bzr selftest --subunit`` the subunit stream will no
729
longer include the "log" information for tests which are considered to
730
be 'successes' (success, xfail, skip, etc) (John Arbash Meinel)
735
* Add a new simpler way to generate multiple test variations, by setting
736
the `scenarios` attribute of a test class to a list of scenarios
737
descriptions, then using `load_tests_apply_scenarios`. (See the testing
738
guide and `bzrlib.tests.scenarios`.) Simplify `test_http` using this.
739
(Martin Pool, #597791)
741
* Add ``tests/ssl_certs/ca.crt`` to the required test files list. Test
742
involving the pycurl https test server fail otherwise when running
743
selftest from an installed version. (Vincent Ladeuil, #651706)
745
* Fix tests that failed when run under ``LANG=C``.
746
(Andrew Bennetts, #632387)
748
* Skip tests that needs a bzr source tree when there isn't one. This is
749
needed to successfully run the test suite for installed versions.
750
(Vincent Ladeuil, #644855).
752
* Skip the tests that requires respecting the chmod bits when running as root.
753
(Vincent Ladeuil, #646133)
755
* Suppress the "maximum recursion depth exceeded in __subclasscheck__"
756
warning on stderr emitted during ``test_dict_deepnested`` in
757
``bzrlib/tests/test__bencode.py``. (Andrew Bennetts)
759
* Use tests.TestCaseInTempDir for tests that requires disk resources.
760
(Vincent Ladeuil, #650001)
767
This is the first beta of the 2.3 series, leading up to a 2.3.0
768
release in January or February. Beta releases are suitable for everyday use
769
but may cause some incompatibilities with plugins. Some plugins may need
770
small updates to work with 2.3b1.
772
2.3b1 includes some performance improvements in both speed and memory
773
consumption, some preliminary support for generating a texinfo version of
774
the doc and better support for launchpad. Many changes were made to make
775
our test suite more robust as well as numerous documentation fixes. It
776
improves the common infrastructure for dealing with colocated named
777
branches and foreign branches. We plan to continue with these themes
778
through the 2.3 series.
780
It also includes bug fixes for 2.0.6, 2.1.3 and 2.2.1 and over 40 fixes of
784
External Compatibility Breaks
785
*****************************
792
* Added ``pre_status`` and ``post_status`` hooks. This allows plugins
793
to register custom handlers which will be invoked before/after the
794
standard status output is displayed. (Parth Malwankar)
796
* ``bzr break-lock --config [location]`` can now break config files
797
locks. (Vincent Ladeuil, #525571)
799
* ``bzrlib.config.LockableConfig`` is a base class for config files that
800
needs to be protected against multiple writers. All methods that
801
change a configuration variable value must be decorated with
802
@needs_write_lock (set_option() for example).
803
(Vincent Ladeuil, #525571)
805
* The ``lp:`` prefix will now use your known username (from
806
``bzr launchpad-login``) to expand ``~`` to your username. For example:
807
``bzr launchpad-login user && bzr push lp:~/project/branch`` will now
808
push to ``lp:~user/project/branch``. (John Arbash Meinel)
810
* New development format ``development8-subtree`` which is similar to the
811
``2a`` format and adds subtree support. (Jelmer Vernooij)
816
* Allow using both ``--using`` and ``--diff-options``.
817
(Matthäus G. Chajdas, #234708)
819
* Allow using non-integer bug ID with generic bug trackers.
820
(Alexandre Garnier, #440472)
822
* ``bzr remove`` now just backs up changed files instead of exiting,
823
forcing you to choose to either keep or delete them. Bazaar will now delete
824
the files if they can easily be recovered using revert, otherwise they
825
will be backed up (adding an extension of the form .~#~).
826
(Marius Kruger, #400554)
828
* ``bzr revert`` and ``bzr status`` are up to 15% faster on large trees
829
with many changes by not repeatedly building a list of all file-ids.
832
* Decrease memory consumption when many chk index pages are loaded. (Such
833
as during ``bzr co`` or ``bzr ls -R`` of a large tree.) Often we need to
834
read many chk pages because the individual chk map nodes will be spread
835
randomly. Peak memory for 'bzr ls -R' on a large tree dropped from 396MB
836
down to 247MB, expect even more significant savings on 64-bit platforms.
839
* Decrease peak memory during ``bzr send``. The old code was caching all
840
text content and all inventory strings for all revisions before
841
computing the diffs. Now we only cache as long as there is a child that
842
will need them. Sending 2000 bzr revisions drops from 1.2GB peak to
843
256MB peak. (John Arbash Meinel, #614576)
845
* ``DirState`` internals use a little bit less memory. For bzr.dev it
846
drops the memory from 1MB down to about 800kB. And replaces a few
847
thousand tuples and sets with StaticTuple. (John Arbash Meinel)
849
* Inventory entries now consume less memory (on 32-bit Ubuntu file entries
850
have dropped from 68 bytes to 40, and directory entries from 120 bytes
851
to 48). (Andrew Bennetts)
853
* Reduce peak memory by one copy of compressed text when writing to pack
855
(John Arbash Meinel, #566940)
857
* When building new working trees, default to reading from the repository
858
rather than the source tree unless explicitly requested. (via
859
``--files-from`` and ``--hardlink`` for ``bzr branch`` and
860
``bzr checkout``. Generally, 2a format repositories extract
861
content faster than seeking and reading content from another tree,
862
especially in cold-cache situations. (John Arbash Meinel, #607298)
864
* Add ``__pycache__`` to the default ``ignores`` file. Future releases of
865
Python will use this directory to store bytecodes.
866
(Andrea Corbellini, #626687)
871
* Additional merges after an unrelated branch has been merged with its
872
history no longer crash when deleted files are involved.
873
(Vincent Ladeuil, John Arbash Meinel, #375898)
875
* ``bzr add SYMLINK/FILE`` now works properly when the symlink points to a
876
previously-unversioned directory within the tree: the directory is
877
marked versioned too.
878
(Martin Pool, #192859)
880
* ``bzr clean-tree`` issues a warning if it is unable to delete a file
881
due to ``errno.EACCES`` instead of exiting with an error on Windows.
882
(Parth Malwankar, #430785)
884
* ``bzr commit SYMLINK`` now works, rather than trying to commit the
885
target of the symlink.
886
(Martin Pool, John Arbash Meinel, #128562)
888
* ``bzr ignore PATTERNS`` exits with error if a bad pattern is supplied.
889
``InvalidPattern`` exception error message now shows faulting
891
(Parth Malwankar #300062)
893
* ``bzr upgrade`` now creates the ``backup.bzr`` directory with the same
894
permissions as ``.bzr`` directory on a POSIX OS.
895
(Parth Malwankar, #262450)
897
* CommitBuilder now uses the committer instead of _config.username to generate
898
the revision-id. (Aaron Bentley, #614404)
900
* Configuration files in ``${BZR_HOME}`` are now written in an atomic
901
way which should help avoid problems with concurrent writers.
902
(Vincent Ladeuil, #525571)
904
* CommitBuilder now uses the committer instead of _config.username to generate
905
the revision-id. (Aaron Bentley, #614404)
907
* Configuration files in ``${BZR_HOME}`` are now protected against
908
concurrent writers by using a lock. (Vincent Ladeuil, #525571)
910
* Cope with Microsoft FTP Server and VSFTPd that return reply '250
911
Directory created' when mkdir succeeds. (Martin Pool, #224373)
913
* `decode` parameter to get() method in FtpTransport and GioTransport classes
914
is deprecated. (Alexander Belchenko)
916
* Don't print internal object name when print an invalid revision spec
917
error. (Neil Martinsen-Burrell, #598701)
919
* Don't traceback when a lockdir's ``held/info`` file is corrupt (e.g.
920
contains only NUL bytes). Instead warn the user, and allow ``bzr
921
break-lock`` to remove it. (Andrew Bennetts, #619872)
923
* ``EPIPE`` can be raised during test server shutdown. This happened on
924
gentoo only so far. (Vincent Ladeuil, #627277)
926
* Errors occurring during HTTP(S) test server starts should now be
927
handled cleanly. (Vincent Ladeuil, #392402)
929
* Fix ``AttributeError on parent.children`` when adding a file under a
930
directory that was a symlink in the previous commit.
931
(Martin Pool, #192859)
933
* Fix ``AttributeError: 'NoneType' object has no attribute 'close'`` in
934
``_close_ssh_proc`` when using ``bzr+ssh://``. This was causing
935
connections to pre-1.6 bzr+ssh servers to fail, and causing warnings on
936
stderr in some other circumstances. (Andrew Bennetts, #633745)
938
* Fix spurious paramiko warning on hardy by ensuring that ``selftest``
939
properly remove its warning filter. (Vincent Ladeuil, #625686)
941
* Fix ``AttributeError on parent.children`` when adding a file under a
942
directory that was a symlink in the previous commit.
943
(Martin Pool, #192859)
945
* Fix ``AttributeError: 'NoneType' object has no attribute 'close'`` in
946
``_close_ssh_proc`` when using ``bzr+ssh://``. This was causing
947
connections to pre-1.6 bzr+ssh servers to fail, and causing warnings on
948
stderr in some other circumstances. (Andrew Bennetts, #633745)
950
* Fix a problem in bzr's ``Makefile`` that meant syntax errors in some
951
parts of bzr's source code could cause ``make check-nodocs`` to
952
incorrectly return an exit code of 0.
953
(Vincent Ladeuil, #626667)
955
* ``HTTP/1.1`` test servers now set a ``Content-Length`` header to comply
956
with pedantic ``HTTP/1.1`` clients. (Vincent Ladeuil, #568421)
958
* Most of the leaked threads during selftest are now fixed, allowing the
959
full test suite to pass on gentoo.
960
(Vincent Ladeuil, #392127)
962
* Only call ``setlocale`` in the bzr startup script on posix systems. This
963
avoids an issue with the newer windows C runtimes used by Python 2.6 and
964
later which can mangle bytestrings printed to the console.
965
(Martin [gz], #631350)
967
* `PathNotChild` should not give a traceback.
968
(Martin Pool, #98735)
970
* Prevent ``CHKMap.apply_delta`` from generating non-canonical CHK maps,
971
which can result in "missing referenced chk root keys" errors when
972
fetching from repositories with affected revisions.
973
(Andrew Bennetts, #522637)
975
* Raise ValueError instead of a string exception.
976
(John Arbash Meinel, #586926)
978
* Repositories accessed via a smart server now reject being stacked on a
979
repository in an incompatible format, as is the case when accessing them
980
via other methods. This was causing fetches from those repositories via
981
a smart server (e.g. using ``bzr branch``) to receive invalid data.
982
(Andrew Bennetts, #562380)
984
* Selftest with versions of subunit that support ``stopTestRun`` will no longer
985
error. This error was caused by 2.0 not being updated when upstream
986
python merged the end of run patch, which chose ``stopTestRun`` rather than
987
``done``. (Robert Collins, #571437)
989
* Stop ``AttributeError: 'module' object has no attribute 'ElementTree'``
990
being thrown from ``xml_serializer`` on certain cElementTree setups.
991
(Martin [gz], #254278)
993
* strace test-helper tests cope with the new Ubuntu policy of not allowing
994
users to attach to their own processes by default.
995
(Martin Pool, #626679)
997
* Test classes like ``TestCase``, ``TestLoader``, and ``TestSuite`` should
998
be available from ``bzrlib.tests.*``. They used to be, but were
999
accidentally removed. (John Arbash Meinel, #627438)
1001
* ``Transport.stat`` on a symlink, including a transport pointing directly
1002
to a symlink, now returns information about the symlink.
1005
* Upgrading or fetching from a non-rich-root repository to a rich-root
1006
repository (e.g. from pack-0.92 to 2a) no longer fails with
1007
``'Inter1and2Helper' object has no attribute 'source_repo'``. This was
1008
a regression from Bazaar 2.1. (Andrew Bennetts, #636930)
1013
* Added a builder/writer sphinx extension that can generate texinfo files. The
1014
generated files are syntactically correct but the info navigation nodes
1015
needs more work. (Vincent Ladeuil, #219334)
1017
* First tests defined for sphinx, including a new bzrlib.tests.features.sphinx
1018
to make the tests conditional.
1021
* Fix a lot of references in the docs to the old http://bazaar-vcs.org to
1022
the new http://bazaar.canonical.com or http://wiki.bazaar.canonical.com
1023
(John Arbash Meinel, #617503)
1028
* When passing a file to ``UTF8DirReader`` make sure to close the current
1029
directory file handle after the chdir fails. Otherwise when passing many
1030
filenames into a command line ``bzr status`` we would leak descriptors.
1031
(John Arbash Meinel, #583486)
1033
* `ControlDirFormat` and `ControlDir` have been split out of `BzrDirFormat`
1034
and `BzrDir`, respectively. `ControlDirFormat`
1035
and `ControlDir` should be used as the base classes for new non-.bzr
1038
`BzrDirFormat.register_control_format` has been renamed to
1039
`ControlDirFormat.register_format`.
1041
`BzrDirFormat.register_server_control_format` has been removed.
1043
Probing for control directories is now done by separate objects derived
1044
from `bzrlib.controldir.Prober` and registered using
1045
`bzrlib.controldir.ControlDirFormat.register_prober` or
1046
`bzrlib.controldir.ControlDirFormat.register_server_prober`.
1047
`BzrDirFormat.probe_transport` has been moved onto `Prober`.
1049
`BzrDirFormat.register_format` has been renamed to
1050
`BzrProber.register_bzrdir_format`.
1052
`bzrlib.bzrdir.network_format_registry` has been moved to
1053
`bzrlib.controldir`.
1057
* ``bzrlib.transform.TreeTransformBase.final_kind``,
1058
``bzrlib.transform.TreeTransform.tree_kind`` and
1059
``bzrlib.transform.TransformPreview.tree_kind`` now return None instead
1060
of raising NoSuchFile. (Vincent Ladeuil)
1062
* BzrError subclasses no longer support the name "message" to be used
1063
as an argument for __init__ or in _fmt format specification as this
1064
breaks in some Python versions. errors.LockError.__init__ argument
1065
is now named "msg" instead of earlier "message".
1066
(Parth Malwankar, #603461)
1068
* Configuration files should now use the ``from_string`` constructor rather
1069
than the ``file`` parameter of the ``_get_parser`` method. The later has
1070
been deprecated. ``from_string`` also accept a ``save=True`` parameter to
1071
have the configuration file immediately written to disk.
1074
* Deprecate treating a `PushResult` and `PullResult` as an integer for the
1075
relative change in revno.
1078
* `FileInWrongBranch` is deprecated in favour of `PathNotChild` and no
1082
* ``IniBaseConfig`` objects should now use the ``from_string`` constructor
1083
the rather than the ``file`` parameter of the ``_get_parser`` method. The
1084
later has been deprecated. (Vincent Ladeuil)
1086
* InventoryEntry instances now raise AttributeError if you try to assign
1087
to attributes that are irrelevant to that kind of entry. e.g. setting
1088
``symlink_target`` on an InventoryFile will fail. It is still okay to
1089
read those attributes on any kind of InventoryEntry. The complete list
1090
of affected attributes is: ``executable``, ``text_id``, ``text_sha1``,
1091
``text_size`` (only valid for kind == file); ``symlink_target`` (only
1092
valid for kind == link); and ``reference_revision`` (only valid for kind
1093
== tree-reference). (Andrew Bennetts)
1095
* InventoryEntry objects no longer have ``_put_in_tar`` or
1096
``_put_on_disk`` methods. (Andrew Bennetts)
1098
* The ``get_filename`` parameter in the ``config.IniBaseConfig``
1099
constructor has been deprecated, use the ``file_name`` parameter instead.
1102
* `tree_files` and `internal_tree_files` are now deprecated in favor of
1103
`WorkingTree.open_containing_paths`.
1109
* Remove used and broken code path in ``BranchInitHookParams.__repr__``.
1115
* Avoid spurious failures in ssh tests: wait for the SSH server to
1116
actually finish, rather than just waiting for it to negotiate the key
1117
exchange. (John Arbash Meinel, #626876)
1119
* ``build_tree_contents`` can create symlinks.
1120
(Martin Pool, John Arbash Meinel)
1122
* Catch socket errors to avoid
1123
bt.test_sftp_transport.SSHVendorBadConnection.test_bad_connection_ssh
1124
random failures. (Vincent Ladeuil, #601804)
1126
* HTTP test servers will leak less threads (and sockets) and will not hang on
1127
AIX anymore. (Vincent Ladeuil, #405745)
1129
* On platforms that don't support forking give a nice error message saying so
1130
when ``bzr selftest --parallel=fork`` is used. (Martin [gz], #528730)
1132
* Rearrange thread leak detection code to eliminate global state and make it
1133
possible to extend the reporting. (Martin [gz], #633462)
1135
* The old ``bzr selftest --benchmark`` option has been removed.
1136
<https://launchpad.net/bzr-usertest> is an actively-maintained
1137
macrobenchmark suite.
1140
* The test suite now simply holds log files in memory, rather than writing them
1141
out to disk and then reading them back in and deleting them.
1144
* The way ``bzr selftest --parallel`` generates N partitions of tests to
1145
run in parallel has changed. Instead of splitting the list of tests at
1146
N-1 points, it distributes the tests one-by-one into the partitions in a
1147
round robin fashion. This reduces the total time to run the tests in
1148
parallel because a series of slow tests in the test suite will be
1149
distributed evenly among the parallel test suites, rather than slowing
1150
down just one suite. (Andrew Bennetts)
1152
* Tracebacks from a parameterized test are no longer reported against every
1153
parameterization of that test. This was done by adding a hack to
1154
``bzrlib.tests.clone_test`` so that it no longer causes
1155
testtools.TestCase instances to share a details dict.
